Fuel Booster Capsule soon available on PSO Pumps

The National Institute of Physics have created a fuel booster capsule which is going to be available on PSO Pumps in sometime. According to sources the cost of the capsule is going to be around Rs 5/- which is going to increase the fuel efficiency by 20-30% per tank. The capsule is going to be placed in a fuel tank which will result in this increased performance.

Can some chemist/physicist or an expert shed some light on how this is possible ? Also lets say even if this is the case is there any possibility of having engine issues because of this ?

Are you thinking what I'm thinking that I think that you're thinking I'm thinking because if you think that I think what I think I'm thinking then we've got a problem?

Fuel Saving Pills/tablets - by pak scientists at 5 pkr / 32 L

Just watched news on Geo TV, Pakistani scientists have developed fuel saving tablets that will be available very soon at PSO outlets at a cost of 5 PKR / tablet and sufficient for 32L Petrol in a tank.
No detail given by TV regarding its composition and the basis of its mechanism. I searched google pakistan and PSO but found nothing.
Anybody has details and its effectiveness?
Thanks,

The pills can act like catalyst, enhancing combustion efficiency. This efficiency in turn reduces gasoline consumption, however as found on net similar pills are available in other countries and its not a breakthrough in Pakistan. Or may be now petrol is getting more expensive and even a slight saving is considered important compared to old times in pak or elsewhere and this way pills can get importance.

I read an article about it fee years ago. It was about all these additives and aftermarket kits to increase your mileage. Most of these are bogus or don't show results as advertised.
The fact is that just by changing your driving habits . You can get better mileage rather than using these so called pills. Avoid jerky starts. not making Engine roar at idling or while driving by pressing accelerator for no reason, keeping tires properly inflated, proper required engine maintenance, proper oil changes plus air filter and so on.

EPA has tested hundreds of such products and did extensive testing and not a single one came put to be true as advertised.

I m not an expert but as I read on various automotive blogs and These additives or pills are useless..
